Limit code use to specific products

[pixelmachine]

Hey,

I'm setting up a site where Gift Vouchers are primarily used in-person. As such we don't have redemption field in the checkout, instead we have a custom page where staff can redeem codes. This works great.

However they have now also requested that vouchers can be used against some specific items in the shop.

I'm thinking to hook into the afterSaveCode event and programatically create a coupon code with matching the voucher codeKey.

This would allow a customer to use the voucher code in the coupon code field and allow me to setup usage rules.

I guess I would then also need to hook into some commerce event to redeem the voucher if the coupon is redeemed. If I can figure out which event to use.

Does this make sense? Is there a simpler way?

Yep, at the moment there's no way to say "I only want vouchers to be redeemable on these products" (or the reverse), but it's something we might eventually build in. While vouchers are similar to discounts, we can't use the "Promotable" setting for products, like you can to disable certain products from having coupon codes and discounts applied to them.

If I'm on the right track with your question?

I'm not sure how you generate your codes, but if it's just about determining which products can have a voucher applied to them, there's the EVENT_AFTER_VOUCHER_ADJUSTMENTS_CREATED event where you can check against the product having a voucher applied to.

Yep that's what I meant.

I think that sounds simpler but it does mean we'd need to have two fields in the checkout, one for coupons and one for vouchers as both would be in use. Right?

Our codes are generated in the normal way when vouchers are purchased through Commerce.

You can use a single form for both discounts and vouchers - it just has to be the Gift Voucher form

The docs say:
Use the following template code and add it to your cart page (ideally near the coupon form if you're using that).

But it can also replace the coupon form?

[engram-design]

Correct, yes. I'll admit the docs aren't worded the best there

Thanks, I'm going to try this out. I assume that matching (or not matching) specific products shouldn't be too complex, however making sure the correct amount is redeemed I guess could get tricky.
